# Prototype of a functional scripting language. Just fooling around. Nothing to see here.

#
A long comment.
Very long, they say.
#

# There's only one data type: list
# Assign variables with :

# Create a list
l: 1 2 3

# Concatenate lists
l2: l 4 5 6

# A statement without an = is a print statement
l2      # Output: 1 2 3 4 5 6
"hello" # Output hello

# Functions
even: mod 2 is 0

# Use the function
evens: filter even l2
evens # Output: 2 4 6

# Every variable which is not defined before use
# is a parameter
add:
  a + b

# Variables and functions are the same
sum: reduce add l2
sum # Output: 1+2+3+4+5+6 = 21

# Classes are functions
# Creates a person constructor with public members name and gender
person name gender

# Inheritance
student person id
  id # Private member

p1: "hans" "male"
s1: student p1 1234
s1 # Output: Hans male 1234
